Light-Based Deep Brain Stimulation Relieves Symptoms of Parkinson’s Disease
Biomedical engineers at Duke University have used deep brain stimulation based on light to treat motor dysfunction in an animal model of Parkinson’s disease. Succeeding where earlier attempts have failed, the method promises to provide new insights into why deep brain stimulation works and…
In vivo quantification of excitation and kilohertz frequency block of the rat vagus nerve
Effort lead by Research Director Nikki Pelot
Continuous deep brain stimulation of the subthalamic nucleus may not modulate beta bursts in patients with Parkinson’s disease
Publication of our latest work exploring feedback signals for closed-loop deep brain stimulation. Steve Schmidt led our effort to quantify "beta bursts" in persons with Parkinson's disease, with and without DBS ...
